    I don't know if you can see the contents of a remote folder and load each one
  • w
    what are you trying to do?
  • k
    im creating a mmorpg where players can collect items and dress up chat etc. im going for desktop targets so what im trying to do is let the app load the items images from a remote server so that when i add new ones there wouldnt be a need to update the app
  • w
    if it's an MMOrpg you'll probably be recompiling/releasing it frequently anyway
  • w
    but rather than having your client search a remote directory for corresponding files the server should have some api that lets you request a list of file urls pertaining to some category
  • m
    How careful / consistent are any of you with properly `put()`'ing the FlxPoints, FlxRects, etc? I've noticed there are some inconsistency in the flixel code such as in 
    FlxBitmapFont
    where it is just set to null instead of being 
    put
    into the pool (https://github.com/HaxeFlixel/flixel/blob/dev/flixel/graphics/frames/FlxBitmapFont.hx#L99) Is that intentional? I'm basically doing a cleanup pass in my code base and noticing some of that in various flixel classes.

    thanks, one more thing tho im creating a game like cube crush. when adding my cubes the fps drops. is there any way i can optimize this

    I'm not going to try to read that code - try pasting in the code tags... But, off the top of my head - you are always going to have at most 
    Width * height
    squares in your game? don't add new ones - just make the max you'll ever need, 
    kill
    them, and 
    revive
    them as needed

    so i have 3 cubes that add randomly in a tile map consisting of 15 rows and columns so ill need 225 cubes how can i achieve this
  • w
    use code tags, like SeiferTim said, like this \`\`\`hx // code here \`\`\`
  • k
    Copy code
    hx
package;

import flixel.FlxSprite;
import flixel.system.FlxAssets.FlxGraphicAsset;


class Tile extends FlxSprite
{
    public var type:Int;
    public var col:Int;
    public var row:Int;
    
    
    public function new(?X:Float = 0, ?Y:Float = 0, ?SimpleGraphic:FlxGraphicAsset, r:Int, c:Int, t:Int){
        super(X, Y, SimpleGraphic);
        
        row = r;
        col = c;
        type = t;
    }
    
    override public function update(elapsed:Float){
        super.update(elapsed);
    }

    my cubes are 25 x 25 pixels each
  • w
    https://snippets.haxeflixel.com/groups/recycling/ Flx groups allow you to recycle members that have been killed
  • w
    You should be using FlxTypedGroups instead of arrays to begin with
  • s
    maybe this is more of an openfl question but is there how to apply like an alpha value to an entire spritesheet instead of to specific objects?
  • s
    code-wise
  • w
    Like you want to set the alpha for all sprites using a certain image without setting them all individually?
  • s
    uh huh
  • w
    You can edit the bitmapData of the graphic they are using. But i think i would just put them all in a group and set their alpha iteratively
  • w
    Changing bitmap data is costly and hard to undo
  • s
    mhm
  • s
    i guess i'll just edit the image then thats probably better
  • w
    I doubt it
  • w
    Could also put them all in a sprite group and set the sprite groups alpha
  • s
    yeye
  • s
    but thank you anyways

    Just hit a case I often hit - not flixel - openfl HaxeUI. Changed the UI yesterday - still builds with the old wrong UI layout from vscode. Build from powershell with 
    lime test hl -debug
    and it's fine. Go back to vscode and build and it's still wrong. I hit this with HaxeUI intermittently - still haven't found the cache - usually just blowing away Exports/hl is enough but that doesn't explain how powershell is getting clean builds. Unless that cleans the relevant cached bits too. Actually just clean the export and it still built incorrectly so that ain't it.
